Home Price Growth, Sales Could Face Headwinds in 2018

David M. Blitzer, CEO of the S&P Indices Committee, said that 2018 may bring challenges to home price growth. Mr. Blitzer said that while strong labor markets, economic growth, and low mortgage rates were major factors driving home price growth, higher mortgage rates are expected next year. Rising rates would make buying a home less affordable for some. Home price growth continued to outstrip inflation and income growth.

Mr. Blitzer cited an Urban Institute report that indicated that high-priced metro areas may compel would-be home buyers to consider renting. High-demand metro areas are subject to high rates of buyer competition and bidding wars can drive affordable home prices beyond the reach of first-time and moderate-income buyers. Significant numbers of buyers turning to rentals could drop the demand for homes and possible ease the rate of home price growth.

Analysts expected home prices to continue increasing due to low supplies and high demand. Millennials are entering their home-buying years and relatively low mortgage rates have supported affordability, but higher mortgage rates and continued competition from investors and cash buyers could stifle demand for homes in the new year.
